HCPCS 75563

Cardiac magnetic resonance imaging for morphology and function without contrast material, followed by contrast material(s) and further sequences; with stress imaging

AI EXPLANATION: A cardiac stress MRI is a noninvasive diagnostic scan that produces detailed images of the heart's structure and pumping function. The test uses a powerful magnetic field and radio waves rather than radiation. During the exam, images of the heart are captured at rest and under simulated physical exertion created by a specialized medication. A contrast agent is also delivered through an intravenous line to help clearly outline blood vessels, highlight blood flow patterns, and reveal any areas of scar tissue or reduced circulation in the heart muscle.
